7.39682 is the answer since one liter is equal to 1.05669 quarts
1.05669 x 7 = 7.39682
therefore, the answer is 7.39682

The length and width of a rectangle are 7 cm and (x-8) cm respectively. Find the value of x if the area with of the rectangle is

Tcecarenko [31]

to find the area of a rectangle is LxW=A

plug in the given numbers you have

L = 7

W = x-8

A = 42

7 * x-8 = 42

7x-56= 42

solve for X

Does anyone know how to solve this?

Charra [1.4K]

Answer:

$\frac{\sqrt{2}}{2}$

Step-by-step explanation:

This almost looks like the left hand side of the following identity:

$\sin(A)\cos(B)-\sin(B)\cos(A)=\sin(A-B)$ .

Here are similar identities in the same category as the above:

$\sin(A)\cos(B)+\sin(B)\cos(A)=\sin(A+B)$

$\cos(A)\cos(B)-\sin(A)\sin(B)=\cos(A+B)$

$\cos(A)\cos(B)+\sin(A)\sin(B)=\cos(A-B)$

Things to notice: 90-76=14. and 90-59=31.

This means we will possibly want to use the following co-function identities:

$\cos(90-A)=\sin(A)$

$\sin(90-A)=\cos(A)$

So let's begin:

$\sin(76)\cos(31)-\sin(14)\cos(59)$

Applying the co-function identities:

$\cos(14)\cos(31)-\sin(14)\sin(31)$

Applying one of the difference identities above with cosine:

$\cos(31+14)$

$\cos(45)$

45 is a special angle so $\cos(45)$ is something you find off most unit circles in any trigonometry class.

$\cos(45)=\frac{\sqrt{2}}{2}$
